A

as limiting myself in this respect. This body B, The front portion of the block or casting B is as herein disclosed, is hex gonal in form and, as formed to provide two vertically spaced cham- 56 illustrated in the accompanying drawings, said bers 20 and 2|, separated by a partition 22. The 5 central portion of the upper chamber 20 has in communication therewith an inlet port 23 opening out through the front face 3 of the block and which is adapted to be placed in communication with a source of fluid under pressure. The central portion of the lower chamber 2| also has in communication therewith an outlet port 24 opening out through the front face 3 of the block B and adapted to have coupled thereto a pipe line leading to a suitable point of delivery.

The rear portion of the block B is formed 'to provide the transversely spaced chambers 25 and 26, separated by an intermediate partition 21. The rear portion of the block or casting B has a port 28 communicating with the upper chamber 25 and with a port 29 communicating with the lower chamber 26. When the port 28 serves as an outlet, the port 29 is serving as an inlet or return and vice versa. For example, if the ports 28 and 29 are in communication with the opposite endsof a line having a turbine interposed therein, the direction of rotation of the turbine can be readily reversed by changing the direction of flow through the ports 28 and 29 without in any way effecting the standard direction of flow through the ports 23 and 24.

The upper chamber 20 is in communication with the upper part of the opening 6 through a port 30 and diametrically opposed to this port 30 is a port 3| affording communication with the chamber 25 at the rear of the block B. The chamber 2| is in communication with the lower portion of the opening 6 through a port 32 and diametrically to the port 32, the lower portion of the opening 6 is in communication with the chamber 25 through a port 33. The valve 8 within the opening 6 is provided therethrough with the longitudinally spaced ports 34 and 35 which are so arranged that when one of the ports is in open position, the other port is entirely closed and whereby such reversal of positions of the ports 34 and 35 is obtained upon a quarter turn of the valve member 8.

The port 34 is for coaction with the ports 30 and 3|, while the port 35 is for coaction with the ports 32 and 33.

The second valve member 1 is also provided with the longitudinally spaced ports 36 and 31 also in right angular relation. The upper port 36 is for coaction with the port 38 affording communication between the chamber 26 and the upper portion of the opening 5 and with the port 39 afiording communication between the upper portion and the chamber 20. The lower port 31 is for coaction with the port 40 affording communication between the chamber 26 and the lower portion of the opening 5 and with the port 4| affording communication with the chamber 2|.

It is to be particularly pointed out that when the port 34 of the valve member 6 is in open position, the port 35 is in closed position and vice versa. The port 36 of the valve member 1 is also in closed position when the .port 31 is in open position and it is to be further pointed out that when the port 35 is in closed position, the port 31 is in open position.

In view of the foregoing description when considered in connection with the accompanying drawings, it is believed to be apparent that when the valves 1 and 8 are adjusted to position, the port 34 of the valve member 3 and the port 31 of the valve member 1 are in open position, the outflow will be through the port 26 and the return flow through the port 29 and, of course, by adjusting the valve membersv 1 and 6 to bring the port 35 into open position, together with the port 36, the outflow will be through the port 29 and the return flow through the port 23.

It is also believed to be' obvious that while 'the direction of flow may be reversed with respect to the ports 28 and 29, the flow through the inlet' 23 is always constant as is also the outflow through the port or opening 24.

From the foregoing description it is thought to be obvious that a valve structure constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

2. A valve structure comprising a casing having two spaced chambers within its front portion and two spaced chambers within the rear portion, the partition between one set of chambers being angularly disposed with respect to the partition separating the second set of chambers, one of the first two chambers having an inlet and the other an outlet, a port in communication with each of the chambers of the second pair and disposed through an outer wall thereof, said casing having two valve seat openings positioned between the two pairs of chambers, a wall of each of the chambers having a port in communication with one of the valve seat openings, a valve member working within each of the valve seat openings, each valve member having two ports disposed therethrough at points spaced therealong for register with the ports affording communication with the opening in which the valve member is seated and the chambers at oposite sides of said opening, means for moving the valve members in unison, the mounting of the valve members being such to have a port of one member in closed position and the corresponding port of the second member is inopenpositionandwiththesecondportoionefl valve member open when the second port of the other valve member is closed, and means ior limiting the movement of the valve members in either direction to assure the desired register 0! the ports.

3. A valve structure comprising a casing having two spaced chambers within its front portion and two spaced chambers within the rear portion, the partition between one set of chambers being angularly disposed with respect to the partition separating the second set of chambers, one of the first two chambers having an inlet and the other an outlet, a port in communication with each of the chambers 01 the second pair and disposed through an outer wall thereof, said casing having two valve seat openings positioned between the two pairs of chambers, a wall of each of the chambers having a port in communication with one of the valve seat openings, a valve member working within each of the valve seat openings,
